- THE SCALA REPOSITORY
-################################################################################
-
-This document describes the Scala core (core library and compiler) repository
-and how to build it. For information about Scala as a language, you can visit
-the web site http://www.scala-lang.org/
-
-Part I. The repository layout
---------------------------------------------------------------------------------
-
-Follows the file layout of the Scala repository. Files marked with a † are not
-part of the repository but are either automatically generated by the
-build script or user-created if needed. This is not a complete listing. ::
- scala/
- +--build/ Build products output directory for ant.
- +--build.xml The main Ant build script.
- +--dist/ The destination folder for Scala distributions.
- +--docs/ Documentation and sample code.
- +--lib/ Pre-compiled libraries for the build.
- | +--scala-compiler.jar The stable reference ('starr') compiler jar
- | +--scala-library.jar The stable reference ('starr') library jar
- | +--scala-library-src.jar A snapshot of the source used to build starr.
- | ---ant/ Support libraries for ant.
- +--pull-binary-libs.sh Pulls binary artifacts from remote repository.
- +--push-binary-libs.sh Pushes new binary artifacts and creates sha.

-Part II. Building Scala with SABBUS
---------------------------------------------------------------------------------
-
-SABBUS is the name of the Ant build script used to compile Scala. It is mostly
-automated and takes care of managing the dependencies.
-
-^^^^^^^^^^^^^^^^^^^^^^^^
- LAYERS:
-^^^^^^^^^^^^^^^^^^^^^^^^
-In order to guarantee the bootstrapping of the Scala compiler, SABBUS builds
-Scala in layers. Each layer is a complete compiled Scala compiler and library.
-A superior layer is always compiled by the layer just below it. Here is a short
-description of the four layers that SABBUS uses, from bottom to top:
-
-- ``starr``: the stable reference Scala release which is shared by all the
- developers. It is found in the repository as 'lib/scala-compiler.jar' and
- 'lib/scala-library.jar'. Any committable source code must be compiled directly
- by starr to guarantee the bootstrapping of the compiler.
-
-- ``locker``: the local reference which is compiled by starr and is the work
- compiler in a typical development cycle. When it has been built once, it is
- “frozen” in this state. Updating it to fit the current source code must be
- explicitly requested (see below).
-
-- ``quick``: the layer which is incrementally built when testing changes in the
- compiler or library. This is considered an actual new version when locker is
- up-to-date in relation to the source code.
-
-- ``strap``: a test layer used to check stability of the build.
-
-^^^^^^^^^^^^^^^^^^^^^^^^
- DEPENDENT CHANGES:
-^^^^^^^^^^^^^^^^^^^^^^^^
-SABBUS compiles, for each layer, the Scala library first and the compiler next.
-That means that any changes in the library can immediately be used in the
-compiler without an intermediate build. On the other hand, if building the
-library requires changes in the compiler, a new locker must be built if
-bootstrapping is still possible, or a new starr if it is not.
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^
-REQUIREMENTS FOR SABBUS:
-^^^^^^^^^^^^^^^^^^^^^^^^
-The Scala build system is based on Apache Ant. Most required pre-compiled
-libraries are part of the repository (in 'lib/'). The following however is
-assumed to be installed on the build machine:
-
-- A Java runtime environment (JRE) or SDK 1.6 or above.
-- Apache Ant version 1.7.0 or above.
-- bash (via cygwin for windows)
-- curl
-
-
-Part III. Common use-cases
---------------------------------------------------------------------------------
-- ``./pull-binary-libs.sh``
-
- Downloads all binary artifacts associated with this commit. This requires
- internet access to http://typesafe.artifactoryonline.com/typesafe.
-
-- ``ant -p``
-
- Prints out information about the commonly used ant targets. The interested
- developer can find the rest in the XML files.
-
-- ``ant`` or ``ant build``
-
- A quick compilation (to quick) of your changes using the locker compiler.
-
- - This will rebuild all quick if locker changed.
- - This will also rebuild locker if starr changed.
-
-- ``ln -s build/quick/bin qbin`` (once):
-- ``ant && qbin/scalac -d sandbox sandbox/test.scala && qbin/scala -cp sandbox Test``
-
- Incrementally builds quick, and then uses it to compile and run the file
- ``sandbox/test.scala``. This is a typical debug cycle.
-
-- ``ant replacelocker``
-
- "unfreezes" locker by updating it to match the current source code.
-
- - This will delete quick so as not to mix classes compiled with different
- versions of locker.
-
-- ``ant test``
-
- Tests that your code is working and fit to be committed.
-
- - Runs the test suite and bootstrapping test on quick.
- - You can run the suite only (skipping strap) with 'ant test.suite'.
-
-- ``ant docs``
- Generates the HTML documentation for the library from the sources using the
- scaladoc tool in quick. Note: on most machines this requires more heap than
- is allocate by default. You can adjust the parameters with ANT_OPTS.
- Example command line::
- ANT_OPTS="-Xms512M -Xmx2048M -Xss1M -XX:MaxPermSize=128M" ant docs
-
-- ``ant dist``
-
- Builds a distribution.
-
- - Rebuilds locker from scratch (to make sure it bootstraps).
- - Builds everything twice more and compares bit-to-bit the two builds (to
- make sure it is stable).
- - Runs the test suite (and refuses to build a distribution if it fails).
- - Creates a local distribution in 'dists/latest'.
-
-- ``ant clean``
-
- Removes all temporary build files (locker is preserved).
-
-- ``ant locker.clean``
-
- Removes all build files.
-
-- ``ant all.clean``
-
- Removes all build files (including locker) and all distributions.
-
-Many of these targets offer a variant which runs with -optimise enabled.
-Optimized targets include build-opt, test-opt, dist-opt, fastdist-opt,
-replacestarr-opt, replacelocker-opt, and distpack-opt.
